Cholesterol - something to watch in childhood

Since our office has adopted new screening protocols based on the Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, we have seen many questions and resistance. I suspect the resistance is due to the fact that kids hate needles and parents aren't sure if insurance will cover the cost of labs. Some families simply have a difficult time taking kids to a draw station.

These guidelines cover additional topics, such as blood pressure and tobacco exposure, but I will only discuss the most common questions specific to the cholesterol measurements here. A lipid panel includes the total cholesterol, triglyceride level, high density lipoproteins (HDL, "good" cholesterol), and low density lipoproteins (LDL, "bad" cholesterol). Some labs include other types of lipids.

My office website discusses the basics of cholesterol.

The dietary advice is summarized nicely in CHILD-1 Diet and Nutrition Recommendations -Childhood Nutrition Basics.

Preparing for the lab draw

If your child hates needles, I understand. But some things are important, and in pediatrics we focus on prevention. If we can prevent heart attacks, strokes, and other consequences of unknown risks of heart disease, we should.

Kids can be prepared before going to the lab. NEVER say it won't hurt. Everyone perceives pain differently, but if they know it might pinch or feel like a poke they will be prepared. Remind them it only pokes for a very short time usually and holding still helps it go faster. Tell them there will be a big rubber band called a tourniquet that will squeeze the top of their arm to help make it easier for the needle to find the right spot.

Let them watch this video on lab draws.  (Warning, this video does show a blood vial being filled... some people get queasy just seeing things like this.)

You can practice at home by letting them show you how they will hold still with their arm out. They can look away and take big breaths with a strong forceful blow out each time. You can wipe the arm with a cotton ball or tissue and talk about how that part tickles. Maybe they can pretend they're blowing out candles or they can blow on a pinwheel.

Make sure they are well hydrated with water before going to the lab. Remind the phlebotomist (who draws the blood) that studies show blowing out upon the insertion of the needle has been shown to decrease pain with injections, and I suspect also with lab draws. You can also use a video on your smartphone or tablet to distract during the draw.

What affects when you should take a child for the lab?

A child should be on his or her regular diet for 4-6 weeks before testing to reflect the child's true levels. If a child vacationed and ate fast food for a week but typically eats a healthier diet, the levels will be skewed toward the more recently eaten foods. If they often eat poorly, do not alter the diet for the purpose of the lab. Get a baseline that is accurate to their lifestyle.

Illness can also affect lipid levels, so ideally children will be overall healthy when the lab is drawn. If there was a recent significant illness, waiting 4-6 weeks to draw the lab is ideal. Significant illness would be one that requires hospitalization or surgery. If oral steroids were given, it would be best to wait at least 4 weeks. An upper respiratory infection, cough, or typical short term illness should simply be resolved before the draw. You would not need to wait 4-6 weeks for these common illnesses. If you are uncertain if an illness is significant, ask your doctor.

Fasting does not affect the total cholesterol significantly, but it does affect the triglycerides. It is recommended to fast 8-12 hours before having the triglycerides checked. This is most easily done by having children drink water in the morning without food or other drinks. Take them to the lab for the lab draw and then let them eat breakfast.

If it is not possible to take kids to the lab when they have fasted, be sure the lab knows that it is a non-fasting level. They will include this with the report so the doctor can evaluate the lab values with that important information. In general I do not enforce fasting if it is too inconvenient unless there is a history of a previous elevated triglyceride. If the triglyceride level has been high on a previous lab, it is important to do a fasting level to see if it is a real risk or due to a recent meal.

Why do we need to check cholesterol in children- isn't heart disease an adult problem?

We know that obesity increases the risk of having a high cholesterol and atherosclerosis.
Elevated triglyceride levels and obesity are associated with Type 2 diabetes. Children with obesity need routine monitoring of their cholesterol along with other chronic disease indicators.

Multiple studies show that parents often perceive their children to be a healthy weight, but in reality their diet and exercise are not healthy and their height and weight do not indicate health.

We know that a family history of people with high cholesterol or certain heart conditions increases the risk. Tobacco exposure increases the risk. Certain chronic diseases increase the risk of cardiac problems. All of these can be risks in otherwise healthy appearing children.

There are a significant number of children who have no known risk factors yet have an elevated lipid level. This can put them at risk for cardiovascular disease, but if it is known, steps can be done to lower that risk.

The simple answer is atherosclerosis (clogging of arteries) can begin in childhood, but has no symptoms at the early stages when treatment is most effective. There are some people who have a genetic predisposition to this despite healthy habits and an outward appearance of health.

Screening recommendations are done by age and risk.

Many things can alter the risk of cardiovascular disease, including genetics, recent illness, puberty, obesity, blood pressure and tobacco exposure. Guidelines take into account these factors to help determine when testing should be done. If risk factors are identified, a lipid panel should be done. All children, regardless of risks should be checked at 9-11 years and again at 17-21 years of age. If the levels are normal, a lipid panel should be repeated in 5 years. If abnormal or if risk factors change, the level will need to be repeated sooner, depending on risk.

From page 8 of the Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents Summary Report 

What are you going to do with the results?

Many parents are frustrated if we find an elevated level but then "don't do anything about it." We are doing something. We just don't start with medicines because medicines are not the best answer. We recommend a healthy diet and daily exercise. Those two things are more important than many parents realize. They can make changes that benefit your child for life. But they must be done. Making healthy changes for the entire family benefits everyone and makes it easier for a child to comply with recommendations.

Repeat levels will be required to see if the diet and exercise changes make an impact. If the results are consistently elevated or significantly elevated to require medication, a referral to a pediatric lipid specialist is indicated.

If you have questions about cholesterol screening for your child, please talk to your child's doctor.

Nutrition For the Picky Eater

I am frequently asked about how to get kids to eat. In general, there are a few quick "rules":

• Don't offer junk. Don't make it easily available at home... most kids can't drive to the store!
• Hungry kids will eat what's offered. Let them get hungry between meals. No grazing.
• Not every food group will be eaten at every meal, so use the day to space foods to incorporate a range of nutrition over time. Think of snacks as mini-meals.
• Keep meal time fun.
• Enforce "Taste a bite without a fight" after 3 years of age.
• It's okay to be tricky and fun: add pureed vegetables to things, use yogurt or hummus dips, put food on a stick, arrange food into fun shapes, be creative.
• Juice is not a food.

This is my first attempt at adding video to my blog. I apologize for the tilted view... it looked straight on my camera! YouTube limits the length to 10 minutes, and I ended up at 11 minutes, so it is broken into two shorter segments.

Is an apple a good bedtime treat?

Photo source: Shutterstock

As parents we try to get as many fruits and vegetables in our kids as they will take, so when Junior asks for a bedtime snack, it is tempting to allow a piece of fruit. Sounds healthy, right?  Surely better than ice cream...

An apple is healthy and can be a great part of a healthy snack, but kids (and adults) shouldn't have a high carbohydrate snack before bed without some protein and / or fat.

Why?

When we eat, our body senses the increase in blood sugar and sends out insulin to store the sugar in cells for future energy. An apple (or other fruit) is high in carbohydrates (sugar) and low in fat and protein. Sugars and can be quickly stored, lowering the blood sugar pretty fast unless there is fat or protein to stabilize it.

Fats and proteins are more complex to digest.  They must first be converted into smaller molecules before insulin can store the food for energy.  This allows a more gradual fall of the blood sugar.

Why is this important at bedtime?

We always have some sugar in our blood, ideally 70-100 mg/dl, but rising after eating and falling when fasting (not eating).  Normal sugar levels give our cells energy for all they need to do. We go for many hours without eating again when we sleep all night. If the insulin level is still high after storing all the easy to store carbohydrates but there aren't more molecules from the breakdown of protein or fat around to start storing, the insulin lowers the normal blood sugar to unsafe levels.  This is especially dangerous at night because one early sign that the blood sugar is too low is tiredness, which is unnoticed when asleep.

Diabetics should be especially aware of this response because their body does not regulate insulin normally, and they can suffer from severe low sugar if too much insulin is given without the proper balance of nutrients.

It would be extremely uncommon for a person with normal sugar management to have serious consequences of low blood sugar (such as coma or seizures) from this apple before bed, but without a good sugar level, the body will not get the most benefits of sleep: restoration of the body and growth in children.

So what's my recommendation for that bedtime snack? Go ahead and give that apple-- with a glass of milk, yogurt, peanut butter, cheese, or other food with protein.

And ice cream isn't all that bad as far as a snack that won't lower blood sugar too much... it just has less nutritional value.  So as a fun treat when kids are eating enough fruits and veggies the rest of the day and have gotten exercise and not an overabundance of empty calories, it's okay to have an ice cream once in awhile.  After all, it's made from milk, so not all bad!

Which reminds me of this great Bill Cosby clip: Chocolate Cake  (Who says we can't have a little fun when talking nutrition?)

Taste a Bite Without a Fight

Here's another blog inspired by a facebook question:

Megan Brower Lynberg My 2.5 year old son is super picky and I swear he looks at certain foods and decides not to eat them. I know most parents have the try it rule, or just one bite, but we can't even get him to do that most times. Any suggestions on how to implement that? Or should we just let it go and know that for the most part he gets a balanced diet and hopefully he'll branch out as he gets older?

Picky eating is synonymous with most toddlers and school aged kids. I smile inwardly when parents boast that their one year old will eat anything, unlike "other kids" who are picky, as if the other parents did something wrong.

It is between 15 months and 3 years that kids who used to eat anything go through phases of pickiness. I say phases, because sometimes it is a favorite food one week, only to be "yuck" the next week.  I knew this when my kids were young, so I took pictures of my toddlers devouring things like broccoli, so I could show them later that they did, in fact, love it.  (It didn't help.)

Overall the two biggest food groups kids dislike, vegetables and meats, are two of the most nutritious, so parents fret about how to get the nutrition in.  My general advice: parents decide what foods are offered, kids decide how much they eat.

My kids learned "Taste a bite without a fight" at daycare. Why silly rhymes work, I don't know, but sometimes they do.  I usually advise to enforce a bite after 3 years.  Before this age, they might just be too young to fight the battle yet. They simply don't know how to follow rules until about 3. I have heard of parents turning on the tv so the child mindlessly eats what the parent puts in his mouth. Don't do that! It sets up so many bad eating habits!!!

Until the taste a bite rule can be enforced (and even after that) I like to use hidden foods as nutrients. We are having pumpkin french toast this morning-- pumpkin puree added to the eggs/milk. This is not much vegetable, but more than they would get from a bowl of cereal or standard french toast. If this is done with many meals, it all adds up. Find foods your child likes, then "tweak" to fit in needed nutrients.

Vegetables and fruits can easily be pureed and put into sauces, casseroles, smoothies, and ground meats (meatballs, burgers, meatloaf).  Put a can of beets into the blender with your spaghetti sauce for a funky colored sauce. If your kids don't like sauce on noodles, try making pizza with a zucchini/carrot/beet jazzed up sauce. Some people just finely shred or chop. I find that puree works better because they don't see it and pick it out! There are many recipes for this online and in cookbooks for parents.  Check out my Pinterest Meal Ideas page for starters. (Not all ideas are healthy on this page... some are things I just want to try!)

Putting a cheese sauce over vegetables or offering a dunking sauce (yogurt, catsup, ranch dressing) makes it more acceptable to many kids. 

Add fruits and vegetables to breads or noodles. Most kids love the bread group. Banana bread, pumpkin bread, zucchini bread, spinach noodles, and more are all ways to add a little fruit or vegetable into something they will eat. Yes, they will get more sugar this way, but ...

Try a soup or stew. This is a great time of year to throw things in the crock pot in the morning and come home to the smell of dinner already ready!  

If it's meat he doesn't like (most don't at this age) use other forms of protein and iron (eggs, nuts, legumes, etc). Dairy helps with the protein, but has no iron, so don't only use cheese - a common food they love! You can also try meat hidden in casseroles or in fun forms, but remember there are entire countries of people who don't eat meat. Just make sure your kids are getting the nutrition they need.

Play with the food: make the food fun to eat by arranging into shapes. Use a cookie cutter for fun shapes. Arrange food into a face on the plate. There are many ideas of this online! 

Let kids help prepare the meals in an age/ability safe way, starting with washing vegetables, or arranging them on a plate. Start a garden next season so kids can see the food grow! 

A tip from my mother-in-law: kids will eat anything on a stick or fun appetizer sized! Make roll ups with a tortilla, cream cheese, lunch meats, spinach, or whatever sandwich fillings you use and cut into circles. Put a toothpick in small pieces of fruit or jazzed up meatballs (or load up fruit or vegetables on a skewer for a fun kabob).  

Read books that involve foods. I have put some ideas on my Pinterest Books page. Two of my favorites: "I Will Never Not Ever Eat a Tomato" by Lauren Child and "Green Eggs and Ham" by Dr Seuss. Use the books to stimulate ideas-- like making green eggs!

Above all, try to keep meal time pleasant. It should be a time the family gathers to talk, laugh, and enjoy one another. If the focus is a fight about eating, it is not serving one of the big benefits of eating together.  Work the nutrition in, but keep the meal itself fun!

Post suggestions of what has worked for your family. I always love to hear new tricks!  And if your child is really restricted in foods, talk with your doctor.  Sometimes it's more than just picky!

Kid's Weight is Weighing in my Mind

Reports of increasing obesity levels have been circulating for years on the news.  I see kids in my office regularly who are in the overweight or obese category and we all struggle how to treat this growing problem.  Excess weight in childhood is linked to many health issues such as high cholesterol, diabetes, metabolic syndrome, and it can trigger earlier puberty- leading to overall shorter adult height.  Not to mention the psychological and social implications of bullying, depression, eating disorders, and more.

Why is weight so much more of a problem now than it was years ago? As a child I did not have a perfect diet, yet I was not overweight because we spent most waking moments outside if we weren't in school. My mother packed a dessert in every lunch box.  We ate red meat most days.  We usually had white bread and butter on the table at dinner.  We drank 2% milk and I ate ice cream every night.  But we walked to school-- without a parent by the time I was in 1st grade (gasp!)  There were only a couple tv channels, and Saturday morning was the only time we could watch tv.  We were able to ride bikes, go to a wooded area, play on a nearby playground, dig in the dirt, you name it - we found something to make it fun!  Today's kids are shut up in the house after school watching one of many tv channels or playing video games. Even those who are shuttled to activities get overall less exercise because it is structured differently.  They ride in the car to practice or class, then sit and wait for things to start. They might sit or stand while others are getting instruction. Simply put: they don't get to do things at their own pace with their own creativity for as long as they want.

What to do???  On one hand kids need to learn to make healthy choices to maintain a healthy body weight for height, but on the other hand you don't want to focus so much on weight that they develop eating disorders.  I think this is possible if we focus on the word healthy, not weight.   Starting at school age I ask kids at every well visit if they think they are too heavy, too skinny, too short, or too tall.  If they have a concern, I follow up with something along the line of, "How would you change that?" I am often surprised by the answers, but I can use this very important information to guide how I approach their weight, height, and BMI.  We talk about where they are on the graph, and healthy ways to either stay in a good place or how to get to a better BMI.  I focus on 3 things we all need to be healthy (not healthy weight, but healthy):

1. Healthy eating
2. Exercise (with proper safety equipment- but that's another topic!)
3. Sleep (again, another topic entirely!)

Food is a part of our daily needs, but much more than that. It is a huge part of our lifestyle. We have special meals for celebrations but on a day to day basis it tends to be more repetitive. We all get into ruts of what our kids will eat, so that is what we prepare. The typical kid likes pizza, nuggets, fries, PB&J, burgers, mac and cheese, and a few other select meals.  If we are lucky our kids like one or two vegetables and some fruits.  We might even be able to sneak a whole grain bread in the mix.  If our family is busy we eat on the run-- often prepared foods that are low in nutrition, high in fat and calories, and things our kids think taste good (ie things we won't hear whining about).  We want our kids to be happy, and we don't want to hear they are hungry 30 minutes after the meal is over because they didn't like what was served and chose not to eat, so we tend to cave in and give them what they want.  We as parents need to learn to stop trying to make our kids happy for the moment, but healthy for a life time.

There is often a discrepancy between the child's BMI (body mass index) and the parent's perception of healthy.  The perception of calorie needs and actual calorie needs can be very mismatched.  I have seen a number of parents who worry that their toddler or child won't eat, so they encourage eating in a variety of ways:

• turn on the tv and feed the child while the child is distracted
• reward eating with dessert
• refuse to let the child leave the table until the plate is empty
• allow excessive milk "since at least it's healthy"
• allow snacking throughout the day
• legitimize that a "healthy" snack of goldfish is better than cookies

Any of these are problematic on several levels.  Kids don't learn to respond to their own hunger cues if they are forced to eat.  If offered a choice between a favorite low-nutrition/high fat food and a healthy meal that includes a vegetable, lean protein, whole grain, and low fat milk, which do you think any self-respecting kid would choose?  If they are only offered the healthy meal or no food at all, most kids will eventually eat because they are hungry. No kid will starve to death after 1-2 days of not eating.  They can, however, over time slowly kill themselves with unhealthy habits.  

So what does your child need to eat? Think of the calories used in your child's life and how many they really need.  Calorie needs are based on age, weight, activity level, growing patterns, and more.  

One of my personal pet peeves is the practice of giving treats during and after athletic games. It is not uncommon for kids to get a treat at half time and after every game. Most teams have a schedule of which parent will bring treats for after the game.  Do parents realize how damaging this can be?  

• A 50 pound child playing 15 minutes of basketball burns 39 calories.  Think about how many minutes your child actually plays in a game. Most do not play a full hour, which would burn 158 calories in that 50 pound child.
• A 50 pound child burns 23 calories playing 15 minutes of t-ball, softball, or baseball.  They burn 90 calories in an hour.
• A non-competitive 50 pound soccer player burns 34 calories in 15 min/135 per hour. A competitive player burns 51 calories in 15 min/ 203 in an hour.
• Find your own child's calories burned (must be at least 50 pounds) at CalorieLab.

Now consider those famous treats at games.  Many teams have a half time snack AND an after game treat.  Calories found on brand company websites or NutritionData:

• Typical flavored drinks or juice range 50-90 calories per 6 ounce serving. 
• Potato chips (1 ounce) 158 calories (A common bag size is 2 oz... which is 316 calories and has 1/3 of the child's DAILY recommended fat intake!)
• Fruit roll up (28g) 104 calories
• 1 medium chocolate chip cookie: 48 calories
• Orange slices (1 cup): 85 calories
• Grapes (1 cup): 62 calories
• Apple slices (1 cup): 65 calories

So...Let's say the kids get orange slices (a lot of calories but also good vitamin C, low in fat, and high in fiber) at half time, then a fruit drink and cookie after the game. That totals about 200 calories.  The typical 50 pound soccer player burned 135 calories in a one hour game. They took in more calories than they used.  And I chose the cookie, which has fewer calories than other options (we're not talking nutrition here) and only let them have one...

What's wrong with WATER?  And eating real food after the game.  As a family. Around the table.  That snack is likely to decrease appetite for the next meal, and it isn't needed.  And if they're hungry, they're more likely to eat the healthy foods on their plate.

There are many resources on the web to learn about healthy foods for both kids and parents. Rethink the way you look at how your family eats.


Simple suggestions:

• Offer a fruit and vegetable at every meal. Fill the plate with various colors!
• Picky kids? Hide the vegetable in sauces, offer dips of yogurt or cheese, let kids eat in fun new ways - like with a toothpick. Don't forget to lead by example and eat your veggies!
• Buy whole grains. 
• Choose lean proteins.
• Eat together as a family as often as possible.
• Turn off the tv during meals.
• Encourage the "taste a bite without a fight" rule for kids over 3 years. But don't force more than one bite.
• Don't buy foods and drinks with a lot of empty calories. Save them for special treats. If they aren't in the home, they can't be eaten!
• Drink water instead of juice, flavored drinks, or sodas.
• Choose low fat milk (1% or skim) after 4 years of age. (Whole milk from 1-2 years is okay for the normal weight toddler. 2% milk is okay for the normal weight 2-4 year old.  It is now acceptable for most kids to take in lesser milk fat than previously recommended.) 
• Limit portions on the plate to fist sized. Keep the serving platters off the table.
• Don't skip meals!
• Eat small healthy snacks between meals. Think of fruit, vegetable slices, cheese, and nuts for snacks.
• Don't forget to move every day and get enough sleep!
